Sekiz haftalık iki farklı yürüme programının orta yaşlı kadınlarda aerobik kapasite, kan lipid profili ve homosistein düzeyleri üzerine etkileri

Çalışmamızın amacı sekiz hafta süreli, iki farklı yürüyüş programının orta yaşlı kadınlardaki aerobik kapasite (VO2max), kan lipid profili, homosistein, vitamin B12, ve folik asit düzeyleri üzerine etkisini incelemektir. Bu amaçla çalışmaya 30-50 yaşları arasında 30 sağlıklı bayan dahil edildi ve bunlar; hızlı tempo yürüyüş grubu (HTYG; n= 10), orta tempo yürüyüş grubu (OTYG; n=10) ve kontrol grubu (KG; n= 10) olarak 3 gruba ayrıldı. Egzersiz grupları, haftada beş gün, günde 30 dakikadan başlayarak 48 dakikaya kadar sabit bir şekilde artan sürelerde yürüdüler. HTYG kalp atım sayısı yedeğinin yaklaşık ~%71 şiddetinde ve ~6.85$\pm$0.32 km/s hızla; OTYG ise kalp atım sayısı yedeğinin ~%51 şiddetinde ve ~5.20±0.14km/s hızla yürüdü. Antrenman periyodundan önce ve sonra maksimal oksijen tüketimi (VÖ2max), kan basınçları, total kolesterol (TK), trigliserid (TG), yüksek yoğunluklu lipoprotein kolesterol (HDL-K), düşük yoğunluklu lipoprotein kolesterol (LDL-K), homosistein, Vitamin B12, folik asit düzeyleri ölçüldü.

The effect of two different eight-week walking programs on aerobic capacity, blood lipid profile, and homocysteine levels in middle-aged women

The aim of the study was to investigate the effect of two different eight-week walking programs on aerobic capacity (VO2maxA blood lipid profile, homocysteine (Hey),.vitamin B12, and folic acid levels in the middle-aged women. For this purpose, 30 healthy women (aged between 30-50 years) enrolled in the study and were divided into three groups as: brisk walking group (BWG; n=10), moderate tempo walking group (MTWG; n=10) and control group (CG; n=10). Exercise groups walked for eight weeks, five days per week from 30min per day steadily increasing up to 48min. BWG and MTWG walked at -71% heart rate reserve (HRR), and at ~51%HRR; at the speed of ~6.85±0.32km/h and ~5.20$\pm$0.14km/h, respectively. Maximal oxygen consumption (VO2max), blood pressures, serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), Hey, vitamin B12, folic acid levels were measured before and after the study. Favoring BWG, VO2max increased (p<0.01); Systolic blood pressure (SBP) decreased (p<0.05) in both exercise groups. Despite no change in TC, HDL-C increased (p<0.01), LDL-C decreased (p<0.05) in exercise groups. While Hey increased (p<0.05) in exercise groups, vitamin B12 levels decreased in BWG (p<0.05) and tended to decrease in MTWG (p=0.Q59). Folic acid levels of BWG reduced (p<0.05). In conclusion, we determined that walking with high tempo increased aerobic capacity more dominantly, but that both type of walking resulted in similar positive effects on blood lipid profiles and SBP. The increasing effect of both walking types on Hey is thought to be related to the decrease in vitamin B12 and folic acid levels.
